To a/ZZ whom t may concern.-

Be itV known `that I, JOHN KEATs, of .Bag-

Vnall Hall, in the county of Staiord, England,

have invented certain new and useful Improvements in Machinery for Winding Thread uponStarShaped Disk-Holders, of which the following is a specification, and for which patents have been obtained as follows: In Great Britain, No. 878, dated January 14, 1893; in France, No. 233,081, dated September 27, 1893, and in Canada, No. 46,397, dated June 20, 1894. j

This invention relates to a novel construction ot' thread-winder, whereby thread may be wound on star-shaped disks withgreat regularity and speed,either in bulk or in pattern, as desired, the laps of thread being made alternately on opposite sides of the thread-holder and upon each spur or arm in succession, or on two spurs or arms in succession.

The machine which I am about to describe is constructed to lill two holders at the same time, but it may be made to take one holder only, if desired.

The invention further relates to the meas-l uring of the thread as it is wound on the holders, and the automatic registering of the lengths wound on the holders.

In the accompanying drawings, Figures 1 and 1 are side elevations of the improved machine iitted with star-shaped thread-holders, and Figs. 2 and 2a are plan views of -thesame Fig. 3 is a front elevation ofthe counting apparatus, and Fig. 4 is a vertical section of the same. Figs. 5 and 6 are detached views of the thread-guide or thread-layer with the parts in connection therewith. Fig.7 represents a plan view, partly in section, of the drivingshaft and certain other shafts of the machine and their attached and adjacent parts, which will be hereinafter explained. Fig. 8 represents a vertical section taken at right angles to Fig. 1, approximately in the line of the Winder-shaft, and showing the thread-holder clamps and gearing for driving the windershaft. Fig. 9 represents a Vertical section taken in a direction parallel with Fig. 1, approximately in the line 9 9 of Fig. 8.

A A is the table of the machine, cast with feet at its angles to provide space below the table-top for the drivinggear.

B is the driving-shaft, fitted with a drivingpulley B and a hand-wheel B2. The shaft B is mounted in bearings carried, respectively, by a pendent. bracket Acast with the table A, and a yoke-bracket piece A2, bolted to the side of the table. This driving-shaft is fitted at its inner end with a driving-disk B3, which runs in contact with a similar friction-disk B3* on the transverse shaft C, mounted in bearings carried by pendent brackets A3 A4, cast with the table.

The frictiondisk B3 is free to slide on a feather which connects it with the shaft B. In its boss an annular groove is turned to receive the fork of a clutch-lever B4, by which it is thrown into and out of contact'with the disk of the Vshaft O for the purpose of starting and stopping the machine. The said lever works ou a fixed fulcrum-pin 5*, Figs. l, 2, and 7, fast in the table A. Keyed also to the shaft C is a pinion l, (see Fig. 7,) which gears -into one or other of the change-wheels 2 3 4 5 6 7 8 made fast to each other and to a sliding key D. This key D lits into a longitudinal groove made in a shaft D, mounted in a rocking frame D2. rlhis rocking frame Ais fulcrumed on hollow bosses cast with standards A5 A6, which are bolted onto the bedplate A. This arrangement of rocking frame provides for the movement of the shaft D nearer to or farther from the shaft'C, for the purpose of bringing either of the change-4 wheels 2 to 8 into gear with the pinion 1. The

sliding key D carries rack-teeth, through` which it receives an endwise adjustment.`

These teeth project outward from the groove of the shaft D to receive a nut C2, Figs. 2 and 7, which turns loosely on the shaft D, and is held in place between one end of the rocking frame D2 and a collar d, Fig. 7, fixed to the shaft D. By turning this nut 02a lateral motion is given to the change-wheels, so as to bring any desired ring of teeth into gear with the pinion 1 to suit the Work in hand. To permit of this movement ofthe change-wheels, the rocking frame D2 is pulled forward by means of a link terminating ina knob D3. The change-wheels are then adjusted by means of the nut C2, and when the proper ring of teeth is brought opposite the pinionv l the same are brought into gear, and the new position of the rocking frame is secured by a binding-screw D4, passing through a tapped hole in the table and bearing on the link of the rocking frame.

On the inner end of the shaft D is a spur-f pinion 9, Fig. 2, which gears into an idle- Io wheel 10, Figs. 2 and 8, mounted onta studaxle i, Figs. 8 and 9, carried by a bracketarm D5, Figs. 1,8, and 9, of the rocking frame D2. This idle-wheel gears into a pinion 1l keyed onto a short shaft E, which may be called the winder-shaft. This shaft has its bearings in a forked bracket-standard A7, bolted to the bed-plate A, and within the fork of this bracket the pinion l1, in gear with the idle-wheel 10, is situated. Mounted in line zo with this shaft E, and to the right and left thereof, are pressing devices consisting of sliding and pressing rods E E, which carry on their inner ends loosely-mounted clamping-heads e for the purpose of gripping the star-shaped thread-holders or bobbin E5', titted to the winder-shaftE, and hold them firmly in place while the same are rotated.- The sliding rods are supported in the hollow bosses of the standards A5 A6, on which the 3o rocking frame D2 is mounted, and in these bosses, which act as guides, the rods are moved to and from the Winder-shaft by means of toggle-levers E2, Fig. 8, actuated by handles E3.

The Winder-shaft at either end terminates in a central stud, and is fitted also with an eccentricpin to receive the thread-holders and carry them round as the shaft is driven by the gearing above described.

The thread-holders used in this machine may be of various diameters and have a greater or lesser number of arms or spurs, it being understood that an odd number is essential to my system of progressive winding.

I have said that the Vmachine is provided with seven change-.gear wheels. rlhis number is adopted to correspond with the number of changes in the winding which I find it desirable to effect. Thus I may lay the thread 5o to the right orleft of each succeeding spur or arm of the rotating holder, whether the holder has live, seven, nine, or eleven spurs; or, taking the larger sizes of holders, I may lay the thread over every two succeeding spurs, and in this case I produce an ever-changing circular progressive movement of the thread on the holder, by which means a large quantity of thread can be piled up on the holder; but in what I call single winding a marked 6o pattern is .produced in the work and a less quantity of thread is accumulated on the.

holder. Y

The numerals on the shaft D, viz: 7, 9, 5, Il, 7, 9, and ll, are intended to indicate the position which the point of the key D should occupy when the machine has been set with the proper change-wheel to wind either single rotation of the thread-holder.

2 liaise or double disks', with five, seven, nine, or eleven spurs. The machine, as shown in Fig. 2 of the drawings,is set to wind double or over every two succeeding spurs of a sevenspurred disk-holder.

I will now explain the means which I employ for laying the thread upon the holders, and measuring the same as it is wound up, premising that as the mechanisms employed for laying the thread for the two holders are counterparts the one of the other, the wind-` ing only of one holder need be referred to.

As respects the measuring of the thread it will be obvious that one act of measuring will serve for the two threads that are being simultaneously wound.

F F are the thread-layers carried respectively by the arms of their rock-shafts F.

F2 are slides mounted in fixed guides F3, made fast to a pedestal bolted on the bedplateA. The slides F2 are fitted with centers which carry their respective rock-shafts F.

Made fast to each rock-shaft isa pendent arm Y F4, carrying a horizontal pin, which lies in a groove made to receive it in the upper end of a rock-lever F5. This mechanism is best shown in the detached views, Figs. 5 and 6, where the rock-lever F5 is shown in face View at Fig. 5 and edge View at Fig. 6 as connected through a bowl with a grooved cam F6, keyed to the shaft C.

It will now be understood that as the shaft C is rotated its cams F6 will rock the levers F5 and cause them to impart an oscillating motion to their respective thread-layers F.

By reference to the plan view, Fig. 2, it will be seen that the slide F2 is slottedcentrally at its inner end to aord free space for thc An inclined extensionf, Fig. 2, of this slide at one side of the slot bears against a pin f on the under side of the sliding and pressing rod E', it being held up to the pin bythe tension of the coiled spring F7, Figs. l and 6. The object of mounting the thread-layer on a slide which receives a tendency to approach the holder is to provide an endwise motion for the thread-layer as the thread accumulates on the holder to produce ballingof the thread. As the thread accumulates "it serves to press back the slidel by bearing against the inner end thereof, and thereby automatically adjust the position of the thread-layer to suit the progress of the work.

It will now be understood that on starting the machine (which we will assume has been properly threaded in the manner that will be hereinafter described) the disk-holder willA receive a rapid rotary motion and present its spurs or arms to its thread-guide, which, in its rapid reciprocation, will pass between the arms ,and lay the thread alternately on opposite sides of the succeeding arms, traveling through every slot'or opening in the disk as they are presented, or every other slot, as the casemay be.

When it is desired to lay the thread sepa- IOO ITO

rately on each succeeding armor spur I fasten back the slide F2 by inserting a pin in one of the pin-holes of the slide, (shown at Fig. 2,) which will then fix the position of the oscilv lating thread-layer, keeping it outside the plane of Amotion of the rotating thread-holder.

Then a holder is lled or balled with the.

required amount of thread it is released from the machine by drawing back the sliding and ro pressing rod to the position shown at the left-t hand side of Fig. 2. By this movement the` slide F2 is forced back, the pin of the rod E" the `inclined extension ofthe 2o the thread to be Wound'is led up to and over a guide-pulley G to atension apparatus G2.

From the tension apparatus the thread passes to and around a pulley H, forming part of the measuring apparatus, and from this pulley the thread is led, as shown at Fig; 1

. to the thread-layer F.

The tension apparatus G2 (see Figs. l and 2) consists of two india-rubberv rollers g,I

Vmounted loosely-in a Vpair of arms, one of 3o which is made fast to the case of the measw-'uring apparatus and the other is pivoted to the fixed arm. These rollers are made preferably the one of soft and the other of hard rubber, and they are caused to bite the thread which is led between them by means of a light tension-spring g in -such manner as to avoid the crushing of the thread.

The pulley His keyed to one end of a horizontal shaft H', which turns in bearings in the 4o case of the measuring apparatus. The other end of this shaft carries a loose pulley Hi, which acts simply as a guide for the thread to the second thread-layer. H2 is a worm cut on the shaft H', and gearing into a worm- 'wheel H5, mounted on an arbor h, which forms 'the center of a small dial H4. Immediately below this dial is a larger dial H5, graduated to fifties and hundreds of yards, while the small dialis graduated to single yards. Made 5o fast to the worm-whee1H3is a spur-pinion H5, which gears into a spur-wheel H5, mounted on an arbor h', that forms the center of the dial H5. The arbors h h of the two dials carry one an index-hand' h2 and the other an index- 5 5 hand h2, which are adjustable thereon and serve to point out the progress of the winding. The hand H2 of the smalldial H4 is held by friction to its arbor, but the hand h2 of the dial H5, which may be called the indicator- 6o setting hand, is made fast to its arbor by a Winged nut h4, for the purpose to be presently explained. Y

The amount of thread to be wound on the holders willconstantly var'y, and it is desir- 6 5 able that the working should be automatically Stopped. This Ieffect by causing the indexhand of the'dialeH5, on reaching lthe end' of its course, to release the friction-clutch BF The dial H5, it will be seen, is graduated up to fifteen hundred yards, which may be assumed to indicate the maximum amount of thread to be wound on aholder. Supposing it is desired to wind five hundred yards only, I slacken the indicator-hand, (before starting the machine,) shift it to 500, and make it fast to the arbor by means of the winged nut. 0n starting themachine, the thread which is laid around-the pulley H will, by the Ydraft put uponrit, cause the pulley and its worm-shaft to rotate and thereby set in action the indicator-hands. l

In order that the machine may automatically stop when the hand h5 of the dial H5 points to zero, a notched camI is permanently fastened to the boss of theindicator-hand and serves to hold out'of action a rocking-lever I', one end of which is wedge-shaped and the other end of which is held in contact with the cam I by a spiral spring i, which connects the said lever withlthe table A in such manner as to pull downits wedge-shaped end.Vv This rocking lever I is fulcrumed in a forked standard A8, erected on the table and its wedge-shaped end occupiesa position in front of a verticalylever I3, fulcrumed on astud-pin carried by a` Standard A9. To this vstandard A9 is also fulcrumed a' hand-lever 14,'which may be termed the starting-lever. The head of Vthis lever is T-shaped, and the upper .limb 20 of the T-head serves to carry across pin c', Fig. l,which projects out from opposite sides of the T-head. -One -end of .this pin bears against the back of the lever I3, and the Vother end of the pin is borne upon by a -pressure-spring I5, the use of whichis to lift'the starting-lever I4 from its depressed position.

The lower limb 21 of the T-head reaches down to the clutch-lever B4 before mentioned and stands in front of a lateral projection b (see Fig. 7) of `that lever, so that when the starting-lever is depressed the lower limb of its T-head being moved forward will strike the lateral projection or incline of the clutch- .lever, rock the clutch-lever on its fulcru m,'and

put the friction-clutch into action.

By the depression of the starting-lever the pendent end of the lever I2 will be brought opposite the turned-up extremity b', Fig. 7

of the clutch-lever, and serves as a stop to prevent that lever from yielding to the pull of its tension-spring B5 and throwing the clutchout of action. The starting-lever will be thus left f ree to rise to its normal position under the pressure of its spring l5. It is in this position that the levers I5, I4, and B4 remain while the machine is in action. So soon, however, as the indicator-hand reaches zero the notch of the cam I will vbe presented to the rocking lever I and the springt', beingV then permitted topull down the Wedge-shaped end of the said rocking lever, will cause the said wedge-shaped end to thrust back the IOO lever I3 clear of the clutch-lever, leaving that lever free to take the position shown in Fig. 2, and put the clutch out of action.

The smaller dial and index-hand provide for the Winding of samples, and when the machine is thus/used the Working and stopping the machine will be by hand.

The indicator -hand h3 and its attached notched cam I being fastened to their arbor h by a clamping-nut h4 in such manner that by unscrewing the said nut the said hand can be turned as much or as little as may be desired on the said arbor, provide for the measuring of the thread and the control of the stoppage of the machine With innitesimal exactness after a given amount of thread has been wound on the holder or holders,
